Again nice prominences today on the Sun! Captured with an SHG 700 and processed/stacked using JSol'Ex!

Thanks a lot! I don't sell prints but you can download a higher resolution here if you want to get it printed for yourself www.astrobin.com/full/18ps16/B/

Plus grande focale oui pour la résolution angulaire, et plus grand diamètre pour la limite de diffraction

Avec des poses de 30s du coup pour la petite lunette

Lt Nono @ltno2.bsky.social · 1d

Ce n'est pas qu'une question de taille 😬, la veille à 342mm avec la petite lulu

Lt Nono @ltno2.bsky.social · 1d

Avec la Starfire de 130mm à 670mm de focale. J'ai utilisé la Poseidon avec un filtre Luminance. 60 poses de 15s avec un gain "Unity" (gain de 8, avec 1e- = 1 ADU)

Lemmon juice being squeezed out of the comet C/2025 A6 #astrophotography. Shot this evening but it's really low so it is tough to even think about getting this one done in RGB.
Can you try and solve this one @kat-astro-bot.bsky.social ?

Thanks Bernd....lots of subs 🤓

Lt Nono @ltno2.bsky.social · 2d

The North America, Pelican and gulf of Mexico (yep, not the "gulf of America" 😇) nebulae to which I added SII subs last night from my backyard. SHO is an unusual #Astrophotography 🔭📷 palette but I do like it.
I'm pretty sure @kat-astro-bot.bsky.social will solve this one in a breeze.

Mais non elle n'est pas fade la tienne. Merci Julien!

J'en ai profité pour en faire également une version en HOO ✨

Thank you Bernd!

From my backyard : Summer is going away gracefully, and with it the North America Nebula NGC7000 in the Milky Way plane. I count around 69 000 stars in this #Astrophotography 🔭📷picture!
Can you guess where this is @kat-astro-bot.bsky.social ?

Ah oui en plus si c'est pour des élèves au sud va falloir trouver des filtres qui couvrent des catalogues du sud (SDSS pour Pan- STARRS c'est plutôt hémisphère Nord principalement - enfin c'est ce que j'ai retenu de mes cours au DUAO). Super projet en tous cas!

Lol the Nobels can't even acknowledge women's contribution to discovery. But sure let's acknowledge The Machines.

Headline from an article in Nature this week that states "Prizes must recognize machine contributions to discovery. The future of science will be written by humans and machines together. Awards should reflect that reality."

Very nice shot Bernd! I like this little lizard bathing in the surrounding H-alpha from SH2-126 😍

LBN 437 The Gecko Nebula captured from my dark site in southern France last month 🇫🇷 😊🔭

It was shot on the EdgeHD 8 with Hyperstar for a total integration time of 8 hours in OSC and Mono. The red nebulosity was enhanced with Ha data.

#Astrophotography

@kat-astro-bot.bsky.social‬ what do you see?

The Gecko Nebula LBN 437 is a dark nebula embedded in the red emission nebula SH2-126. It lies at a distance of about 1.200 light years from Earth in the constellation of Lacerta. Its shape resembles a Gecko hence the name 🦎

On October 14, 2025, an exceptional event will be observable by astronomers in Western Europe: #Ganymede, Jupiter's third moon, will #occult a magnitude 7.5 star (HIP 37442), causing a slight decrease in brightness of 0.1 magnitude for 17 minutes.
